Greek mythology is the body of myths and teachings that belong to the ancient Greeks, concerning their gods and heroes, the nature of the world, and the origins and significance of their own cult and ritual practices. It was a part of the religion in ancient Greece.
The gods of the ancient Greek pantheon are divided into various categories. The first of these--the Olympian gods, Titan gods, and primordial gods--represent the three generations of deities to rule the cosmos. The next five categories divide the gods by domain, namely the gods of sky, sea, earth (rustic and agrarian), and underworld. The final sections contain the daemones--minor deities or spirits representing abstract ideas, emotions and conditions--and apotheosed mortals.
